nBusiness analyst are suppose to be the requirement definer who will be able to define all the requirement of the project from the starting of the project(s). This is the job of Business analyst in tradition requirement analysis.

He should communicate properly with the customer and refine the needs of the customer. He should be able to satisfy the customer(s) need.What is Agile Project Management?
This SE assumes that process required to develop working software in todays economy is not predictable. Requirement may change, technology may change we can predict individual team members efficiency. When the factors that affect engineering are not static we can’t predict the outcome within sufficient tolerance. Instead we need to adjust the outcome and guide them to create desired outcome. Agile project management does this by creating a high level visibility of the project status, frequently inspecting outcome and maintain the ability to adapt the changing requirement.

In Agile collaborative project requirement succeeds. All the team members are from all discipline involved in defining project requirement. Technical team members and Quality Assurance (QA) collaborate with the product owner and the BA to develop the project specifications. So Team members in Agile project management can experience the collaborative business process involved in the product engineering.Then Who is Agile Business Analyst?
